Biography of Upendranath Brahmachari

Upendranath was a famous Indian scientist and a leading medical practitioner of his time. He was a remarkable personality. He worked from 1915 on a cure of Kala-azar, a dreaded killer in Bengal and Assam. The traditional treatment by antimony (stibium in Latin) was long, tedious and painful, and therefore impracticable. In 1920, Brahmachari discovered and organic compound of antimony, which he called Urea Stibamine. It had no painful effects and determined an effective substitute for the other antimony containing compounds in the treatment of Kala-azar (Visceral Leishmaniasis ), which is caused by a protozoon, leishmania donovani. It was used on an experimental basis in Assam in 1923 and on a mass scale from 1928. By 1933, about 3.25 lakh lives had been saved in Assam alone. The medicine has also been used successfully in Greece, France and China; but contary to popular belief, it was never patented.

His discovery on Kala-azar led to the saving of millions of lives in India, particularly in the erstwhile province of Assam, where several villages were completely depopulated by the devastating disease. The achievement of Dr. Brahmachari was a milestone in successful application of science in medical treatment in the years before arrival of antibiotics, when there were few specific drugs, except quinine for malaria, iron for anemia, digitalis for heart diseases and arsenic for syphilis. All other ailments were treated symptomatically by palliative methods. Urea Stibamine was thus a significant addition to the arsenal of specific medicines.
